Description

Oxirane, Methyl-, Polymer With Oxirane, Ether With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol (3:1) is a specialized polyether polyol, a key reactive intermediate in polyurethane chemistry. This compound matters for its role as a versatile building block, offering controlled molecular weight and hydroxyl functionality to fine-tune the properties of final polymers. Industries requiring high-performance elastomers, coatings, adhesives, and sealants will find this chemical essential for developing products with specific flexibility, durability, and chemical resistance.

Application

• As a key polyol component in the formulation of flexible and rigid polyurethane foams.
• In the synthesis of high-performance polyurethane elastomers for industrial parts and automotive components.
• As a reactive intermediate for urethane acrylates and other radiation-curable oligomers used in coatings and inks.
• In the production of specialty adhesives and sealants requiring excellent adhesion and environmental stability.
• As a modifier and crosslinking agent in epoxy resin systems to enhance toughness.
• For the manufacture of castable polyurethane parts with specific mechanical and thermal properties.

Quality Control

Our Oxirane, Methyl-, Polymer With Oxirane, Ether With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol (3:1) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in hydroxyl value, viscosity, water content, and acid value, meeting the precise requirements of polyurethane formulation. Certificates of Analysis (COA) documenting all key parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen blanket) after opening to prevent moisture uptake and potential oxidation. Keep away from strong oxidizers and heat sources.
